The heat of fusion for water is significantly more than the heat of vaporization for water because fusion requires complete separation of one molecule from another.

Question

Quizplus · Accepted Answer

The statement is incorrect. In fact, the heat of vaporization for water is significantly higher than the heat of fusion because vaporization requires breaking many intermolecular forces holding the molecules of water together, whereas fusion requires breaking only a few intermolecular forces between water molecules. Therefore, more energy is needed to vaporize water than to melt it.
